Did you know that the food can communicate with your cells? The foods we ingest have microRNAs, small cellular pieces that can interfere with messages from our cells to create proteins involved in cell aging, tumor formation, tumor suppression, bone growth and more. MicroRNAs have been researched for over 20 years and thousands of them have been identified in that time. While research in the realm of microRNAs has been heavily focused on cancer we are now starting to see data on how our lifestyle choices, exercise, physical fitness and the type of diet we consume directly affect microRNA levels in our body. In this episode Doc J breaks down why microRNAs may be a way to assess the impact of your diet and lifestyle on your overall health and what diet and lifestyle interventions seem to make the most impact on overall health.
What You’ll Learn In Today’s Episode:
• How herbs and veggies protect us from cancer
• Why diets excluding entire food groups may not benefit us
• How microRNA might be a novel way to measure health status
• How alcohol consumption and physical fitness affect microRNA
